On Preaching to the Dead

For this cause was the Gospel preached also to them that are dead, that they might be judged according to men in the flesh, but live according to God in the spirit. (1 Pet. 4:6)

St. Maximus the Confessor ca. 580-662

Some say that Scriptures call ‘dead’ those who died before the coming of Christ, for instance, those who were at the time of the flood, at Babel, in Sodom, in Egypt, as well as others who in various times and in various ways received various punishments and the terrible misfortune of divine damnation. These people were punished not so much for their ignorance of God as for the offences they imposed on one another. It was to them, according to [St Peter] that the great message of salvation was preached when they were already damned as men in the flesh, that is, when they received, through life in the flesh, punishment for crimes against one another, so that they could live according to God by the spirit, that is, being in hell, they accepted the preaching of the knowledge of God, believing in the Savior who descended into hell to save the dead. So, in order to understand [this] passage in [Holy Scriptures] let us take it in this way: the dead, damned in the human flesh, were preached to precisely for the purpose that they may live according to God by the spirit.
